Khan was a notable adversary early in
Iron Fist's career, fighting Iron Fist,
Luke Cage,
Colleen Wing, and
Misty Knight on numerous occasions as well as sending his agent
Scimitar against them. When Iron Fist contracts radiation poisoning, Luke Cage takes him to
K'un-L'un for treatment. While there, Iron Fist is secretly impersonated by a
H'ylthri, a plant-like alien whose species are ancient enemies of K'un-L'un. Soon after their return to the outside world, the doppelgänger is destroyed as a result of a scheme engineered by Master Khan.
Namor travels to K'un-L'un, where he finds Iron Fist alive. While in stasis with the H'ylthri, Iron Fist had focused his chi to cure his radiation poisoning. After returning to Earth and investigating the apparent invasion of Earth by the H'ylthri, Namor is forced to fight their captive,
Wolverine. The battle is interrupted by Master Khan, who wipes Namor's memory and dumps him in the American Midwest. Namor is missing for almost a year until
Namorita tracks him down using a psychic link to him she had recently discovered. Namor does not regain his memory until sometime afterward, when he is captured by
Doctor Doom. Doom's ship is magically imprisoned in a bottle by Master Khan, who assumes Namor's form. Namor soon breaks the bottle and the spell, and kills Khan. ==Powers and abilities==
